  Effects of microstructural feature, secondary dendrite arm spacing (DAS II) and defects (mainly porosity) in aluminum alloy die castings ADC10 on tensile properties were investigated. Die castings were made using a 882kN cold-chamber die cast machine. The test pieces differed in DAS II and quantity of porosity. The tensile strength and elongation were especially found to increase with the decrease in DAS II and quantity of porosity. Fractures include ductile fracture and brittle fracture. The brittle fracture occurred more easily with higher porosity or DAS II, and the ductile fracture with smaller porosity or DAS II. The greater the specific gravity was above 2.70, the more excellent the tensile strength and quality were found to be.
